Aluminum electrolytic capacitors are polarized electrolytic capacitors with a larger capacitance per unit volume than other capacitors. They are commonly used as many other electronic components such as batteries, resistors and transistors. This article explores the application field and working principle of the specific aluminum electrolytic capacitor model EEV-FK1V4R7R.

EEV-FK1V4R7R is a type of non-solid electrolytic aluminum capacitor. It works by using a pool of electrolyte fluid called a conductive medium containing cations (positively charged ions) and anions (negatively charged ions). An electric field is created when a voltage is applied to these two electrodes. When electrons flow through this electric field, positive ions move towards the negative electrode, and negative ions move towards the positive electrode. This creates a diode that allows for charge storage and energy transfer.

In terms of application field, EEV-FK1V4R7R is a good choice for applications that require a high capacitance value and a low leakage current. It can be used in numerous applications such as DC power supplies, high-frequency switching power supplies, filters, input/output capacitors of attenuators and impact sensors. It also has the advantage of being an electrolytic capacitor, meaning it can store a more significant amount of energy than its non-electrolytic counterparts. This is very beneficial in power electronics.

The working principle of EEV-FK1V4R7R is based on the electric fields generated by the two electrodes. The two electrodes are an anode and a cathode. The anode is a sheet of aluminum which is covered with an oxide layer while the cathode is a small tube through which the electrolyte is passed. The electrolyte is typically a solution of boric acid and water. When the voltage is applied, an electric field builds up in between the two electrodes generating current that sustains the electric field. This causes ions to move from the electrolyte, which accumulate onto the oxide coated aluminum surface.

The electric field set up by EEV-FK1V4R7R helps to store energy, which is released when the capacitor is discharged. This occurs when the voltage across the capacitor drops below the breakdown voltage, resulting in the current decreasing until the electric field vanishes. This process helps to sustain the charge stored in the electrolyte which is eventually released when the voltage is re-applied.

In summary, EEV-FK1V4R7R is a type of non-solid electrolytic aluminum capacitor that is suitable for applications that require a high capacitance value and a low leakage current. It works by generating an electric field between the two electrodes due to the presence of an electrolyte which allows for charge storage and energy transfer. It is used widely across the electrical industry due to its high storage capacity and fast discharge time.
